Shoe storage... could paint the pvc a fun color and put it in the boys room...

DIY: PVC Pipe Shoe Storage - so fun and so simple, could easily spray paint or cover in fabric or paper too. maybe a horizontal layout of two rows or something. I think this would be good for garage "yard shoes" storage

I love the hidden storage and the option for more than one bed for sleepovers, etc.  the builders notes are great for small improvements.  It seems very customizable too and this is the first thing she ever built! amazing

Queen size playhouse loft bed - forget the castle bed, this is it! The slide goes across the front, and the whole thing fits a queen-sized mattress?the slide :o)

Love this bunk bed for boys - OMG SO much better than other stuff I've seen!!!!
